Team 929W Summer Robot Reveal

[sDiBer]

This was our reveal for the REX Hosts Skyrise competition on June 21st

Team 929w

-We use a 4-motor drive, 4-motor 1:7 Sir bar, and 2-motor Linear Slide Lift powered by a 36-tooth gear.
-Cube Intake is passive when picking up cubes, but uses pneumatics to release the cubes
-Skyrise Sections are picked up using Stanley Shi’s Friction Plunger
-The Robot is able to pickup and lift 2 cubes, and pickup a skyrise section while holding a cube
-The Robot can build and score on up to 5 Skyrise sections

This robot was the second alliance member of the winning alliance at REX Hosts Skyrise
Let us know what you think!

Our team members are very interested in the design of your lift for your skyrise robot. Would you share the design with our teams? If you could send some picture or a drawing of the lift that would be great.

Thanks

I just wanted to ask out of curiosity, was there a particular reason why your team chose to use both a 4 motor six bar lift, as well as a vertical linear slid lift. I don’t want it to sound critical, I was just wondering if there was a particular design advantage by using both design’s as far as you could tell.

Scoring skyrise sections on a non linear lift is difficult, thus a linear lift+non linear bar lift.

I loved the triple passive intake, it was very clever. Great job, I look foward to seeing your robot as it progresses.

Triple?
I was only able to see 1 passive intake. What are the other two?

I definitely can see what I think are two, but like you I really have no idea what the 3rd is…
1: there is your passive skyrise plunger.
2: the cube intake which can passively intake cubes. But needs pneumatics to release them.
3: ???

Scoring skyrise sections on a non linear lift is difficult, thus a linear lift+non linear bar lift.

When I watched the video, it seemed as though it would be even easier to score if the lift had been an entirely vertical lift. It seems like it would be difficult to aim the skyrise sections or cubes with the bar lift, even before you could make use of the vertical lift. I didn’t know if there was an advantage to using both lift systems over using a solely vertical lift design.

In my opinion this robots usage of a linear lift to fix the problems with the bar lift’s lift arc is bad.
The linear lift added on is a waste of motors. Allocating all motors into a lift that is linear is a better solution.

However if you had a bar lift, adding the linear lift would make it easier to score, thats for sure. I’m saying its better to have a linear lift in the first place.
